It seems that Canada Warblers were easier to see in the Andes than during spring migration at Long Point,Ontario.
This one was taken at high altitude,Guango Lodge,Napo Province but we also saw them much lower down in southern Ecuador

For the first time I witnessed what some referred to as a fallout. There were so many warblers it was hard to keep track of what was moving through. Hopefully an experience to be repeated. Seen at the special location of Long Point, Ontario.
